'1 Claims.

The-present invention; relates. to apmethodof and: an apparatusfor-producing. artificial sausage skins.

Inzthemanufacture air-artificial sausage skins ita isknown to'impregnatethe outeror inner Wallor surface of tubular, fabrics. with. a. suitablefibrous mass consisting, ofsanimal substances such as meat massesv ormeattfibres; Forthis purpose, the tubular fabric is jdrawn upwardlythrough an annular gap and hereby the impregnating mass is; appliedwithin. Oli-=Wi13h01l13 "to, the tubular fabric.

According to the method of the present inven: tionanimpregnatingmassisapplied 'to the tubularfabr-ic simultaneously withoutand within-so that the outeraswell as theinner surface of the-finishedtubular fabric-- is coated with an impregnatinglayer. connection withsuch an impregnation-it is ofparticular'advantage toso carry outthecoating of both 'faces of the-fabric sleevewiththe fibrous material;that the fibres atboth sides or surfaces of the wall of thefabric sleevecross each other. Hereby a special-reiniorcement of" theimpregnation andtherewitha greater strength and durability of the artificialsausageskinis obtained; This is of particular importance ifthe tubularfabrleismadeof arti fi'cial silk which is not as strong asnatural-silkand, moreover, is more sensitive to moisture, Owing to the arrangementof the fibres indireC- tions crossing each other uponthe inner wall andthe outer Wall; oftheartificialisausageskin, the lower; strength of ithe finishedxtubnlar sausage skinxm-ade of artifiicialsilk iscompensatedby the reinforcement of the impregnation and, more! over, thesensitivity; ofrthe artificial silkto moisture, is. renderedin-efiectiveiby; the fact that the tubular fabric iscompl'etely:embedded in the fibrous mass.

The arrangement: of: the fibres-of, the t-Wo-ima pregnatinglayers: in.directions crossin each other: at theinner and": outer surface-of theartificial sausage skin is obtained-in accordance with the; invention bythe". fact that the inner and outerwiper members-for the impregnatingmass are rotated relatively-t. to each. other, while the tubulariabriceis longitudinally drawn along-these irriemloers.v Hereby: the.-fibres; present in. the im'- n fesnat-ing mass: areaadjustedsin thedirection in which the 1 Wiper.- membershmove along: the wall of;

the- .tubular fabric." If; the wiper members are uniformly rotated aboutthe axis ofit-he -mov-ed tubular, iabrimthe, fibres are helicallydirected, but if the inner wiper members rotate in a direction oppositetoe-that: of the outer member, the

fibresare arranged directions crhssing e'aoh other; theangulanpos'it-ion 0f the fibres-'re1a-. tively to eachothercor-responding to the speed of; movement of the tubular fabric; aswellas.

- of the wi er-members;- Depending on the speed selected; the fibres maybe arranged in a more flat or-steep direction and, moreover; theangular-positionupon the inner orouter 'side-or sur face may-hedifferently chosen; if thewiper-memhers are rotated withdifferentspeedswgalso. v

Any desired length of tubular fabric 7c .ispushed upon aqpipe Z which inturn is pushed over the stand 'pipe. 9 and extends to the bottom of thetrough-"a. The end- -(ii-"the; tubular fabric is is Withdrawn from thesupportngpipel and pulled upwardly through the bushing e. Within thelatter a distance member m having a convex surface is mounted upon thepipe 9. The outer diameter of the distance member m is somewhat smallerthan the inner diameter of the bushing 2, so that an annular gap isformed through which the tubular fabric may be drawn.

Within the pipe 9 a long spindle n is rotatably mounted the diameter ofwhich from below the supply pipe it until above the discharge openings zis substantially smaller than the inner diameter of the pipe g, so thatthe impregnating mass may unimpededly be fed upwardly in the pipe g.Both ends of the spindle n are enlarged to the inner diameter of thepipe 9 so that above and below the mass cannot be discharged. To

this purpose, moreover, special sealing means may be provided at theends of the pipe g. The

lower end of the spindle is extended through the pipe 9' and carriesaworm wheel 0 which by means of a cylindrical projection or rim 3) isjournalled in a ball bearing q. The drive of the wormwheel o is effectedby the worm r the shaft 8 of which simultaneously drives the worms andworm wheels of the other devices. The drive may be effected by anelectromotor.

The upper end of thespindle 12 also extends through the pipe g and isprovidedwith a square 75 upon which may be mounted two supporting bodiesu for the innenwiper members 2;. The latter consist of circular discsthe edges of which are rounded off. These discs are rotated by way ofthe supporting bodies a by means of the spindle it. At the outer side orsurface of the tubular fabric 7c another wiper ring w is arranged in alevel between the two inner Wiper members 11. The wiper ring'w is fixedto a Worm wheel as rotated by a worm y the shaft 2 of whichsimultaneously drives the worms of the other devices in the same manneras the lower shaft .9 drives the worms as described above. The Wormwheel it runs on a ball bearing which is supported by way of the boltsor studs 2' from the flange f of the bushing e. I

If the worm wheels 0 and a: are rotated in opposite directions, theinner and outer wiper members 0 and respectively rotate correspondinglyand thereby also correspondingly apply the fibres of the impregnatingmass to the tubular fabric 1 c, so that the fibres upon the inner andouter side respectively cross each other. Details of the device may, ofcourse, be modified without departing from the spirit of the invention.
